Air Quality

AIR QUALITY

To prevent, control and abate air pollution in the country, the Government of India enacted Central legislation called the Air (Prevention & Control of Pollution) Act, 1981 (referred to as the Air Act, 1981). Every polluting industry must obtain a consent from the State Pollution Control Board for the discharge of air pollut­ants in any form through chimney or otherwise. The State Board may lay down suitable conditions while giving consent to discharge air pollutants in the light of emis­sion standards developed by the Central Board, subsequently notified through the rules framed under the Environment (pro­tection) Act, 1986 Rules.
